Causes of damp and mould

Mould and damp are caused by excess moisture. Moisture in buildings can be caused by leaking pipes, rising damp in basements or ground floors, or rain seeping in because of damage to the roof or around window frames.

A newly-built home may be damp if the water used when building it is still drying out – for example, in the plaster on the walls. Excess moisture indoors can also be caused by condensation.

If you have mould or damp it's important to find out why you have excess moisture in your home. When you know what's causing the damp, you can make sure your home is repaired or take steps to limit the moisture in the air. You may need to get a professional to remove mould for you, but if it's only a small amount you may be able to remove it yourself.
